语音回声隐藏技术及分析

The Analysis of Voice Hiding Technology Based on Echo

将信息隐藏技术用于实现语音安全通信,对语音安全通信的一种新方法———语音回声隐藏技术进行了分析和研究,给出了实现该技术的系统方案,并进行仿真和分析,从人耳听觉特性具体要求的角度具体讨论了该系统的实现细节。

In this paper, after explaining the concept of information hiding, we proposed a secure (and convert) voice communication scheme, which can be used in digital communication systems. By introducing echo into voice signal, secret information can be hidden in exoteric information. The performance of this scheme is simulated and analyzed. The detail of the scheme is also discussed from the point of view of the sensitivity of hominine hearing.
